convert list<list<string>> to dictionary<list<string>,int>

Question

Dictionary<List<string>, int> dictionary = input.GroupBy(x => x).ToDictionary(x => x.Key, x =>x.Count());

This isn't working, what should I be doing? GroupBy only compares references of list.So how can I compare elements of list?

input is in List< List < string >> and i need it in a dictionary.

Answer 2

Dictionary<string, int> dictionary = input.GroupBy(x => x).ToDictionary(x => x.Key.toString(), x =>x.Count());
